TEMILE FOR OPHTHALMIC MOUNTINGS.

Specification of Letters Patent.

Patented Ma 28, 1918.

Application filed July 20, 1914. Serial No. 351,912.

To all whom it may concern:

Be it known that we, LAWRENCE PoE'roN and JOEL C. WELLS, citizens of theUnited States, residing at Southbridge, in the county of Worcester andState of Massachusetts, have invented certain new and use fulImprovements in Temples for Ophthalmic Mountings, of which the followingis proved temple for ophthalmic mountings a s ccification.

ur invention relates to improvements in temples and has 'for its leadingobject the provision of a novel, light. inconspicuous and extremelycomfortable temple for use on ophthalmic mountings.

A. further object of our invention is the provision of an improved formof temple which shall combine the strength and durability of the usualmetallic construction with the lightness and comfort of the shell orcomposition type of ophthalmic temple. Another object of our inventionis the provision of an attractive and inconspicudos temple of thisnature of very strong and durable construction, and which shall embodycertain improved structural details, substantially as described.

Other OlJJQCtS and advantages of our imshould be readily apparent byrelevance to the following description taken incoimection with theaccompanying drawings, and it will be understood that We may make any.modifications in the specific details of construction shown anddescribed within the scope of the appended claims without dcparting fromor exceeding the spirit of our invention.

Figure I represents a side elevation of one form of our improved temple.

Fig. II represents a'similar view of a modified construction thereof.

Fig. III represents an enlarged fragmeir tary sectional view of ourtemple in a vertical plane.

Fig. IV represents a similar view thereof taken on a horizontal plane.

In the. drawings, in which similar charactors of reference are employedto denote corresponding parts throughout the several views, the numeral1 designates the temple side, which is preferably formed from gold. goldfilled or other suitable metallic mall rial,

Carried by said metal ic portion, 1

is the supplemental side and ear hook portion 2 formed from shell orsuitable composition material, such as zylowa're, for exam le. p

In igs. III and IV, we have illustrated one manner of attachment of theside and ear hook portions. In this form the side 1 is provided with theexteriorl threaded male member or tang 3, preferali ly c0n'siderablyreduced in size, havin a somewhat flattened portion 4. The mem er 2 ispreferably formed with the socket or female portion as at 5 to receivethe member 3 of the temple side, in use the parts being preferablyscrewed-together to firmly unite the same, the ear hook then being.somewhat heated and pressed around the rejection 3 of the side, when thesame will t against the flattened portion fl so tightly as to preventany unscrewi'n ticularly resilient portion as at 7. This may beaccomplished either by forming the side with or loosening -move-- mentof theparts wlthout first rte-heating a cable portion at this point, asis illustrated in Fig. 1, or by reducin 01' flattenin the side at 7,indicated at *ig. II. In either event additional resiliency is impartedto the temple side at the point '7 ad'acentthe joint so that anytendency to ben near the joint will cause the. bending action to occurat the point 7 and thus eliminate to the greatest possible degreeliability of breakage at the joint portion of the temple.

From the foregoing description the construction of our improved templeshould be readily apparent, and it will be seenthat We have provided atemple embodying the advantages of the metallic side, together withthecomfort and clinging properties of the shell or CUlTlpOSltlOH earhook, and

that in itdditirrl we. have so constructed the temple as to reduc to aminimum any linbihly of breakage ad acent the oint of the looseningofthe parts.

We claim:

1. In a temple for spectacles, the combination with a solid ear piece ofcomparatively large diameter comppsed of celluloid or similar materialand having a recess in its forward end, of a smaller lens attaching wireanchored in the recess of the ear piece by inserting it endwise therein,the recess being substantially the same size as the wire to be insertedtherein, and the wire being formed with lateral projections embedded inthe walls of the recess for anchoring the parts against relativetwisting movement.

2. In a temple for spectacles, the combination with an ear piececomposed of celluloid or similar material and formed with a recess inits forward end, of a smaller lens attaching wire anchored in the recessof the ear piece by inserting it endwise therein, the recess beingsubstantially the same size as the wire to be inserted therein, and theWire being formed with shouldered portions embedded in the walls of therecess for anchoring the parts against longitudinal separating movement.

3. In a temple for spectacles, the combination with an ear piece ofcelluloid or similar material, having a recess in its forward end, of asmaller lens attaching wire anchored in the recess of the ear piece byinserting it endwise therein, the recess being substantially the samesize as the wire to be inserted therein, and the wire being formed withprojections embedded in the Walls of the recess for anchoring the partsagainst relative movement.

4. In a temple for spectacles, the combination of a metallic side pieceterminating n a flattened portion having a shoulder between theflattened portion and the side piece proper, and a nonunetallie earpoi-- tion having an orifice to receive the end of the metal side, saidear portion being compressed over the flattened side portion to preventWithdrawal or twisting of the side portion.

In testimony whereof we aflix our signatures in presence of twowitnesses.
